Brasília, Brazil, January 03, 2005 $#150; BRASIL TELECOM S.A. (NYSE: BTM; BOVESPA: BRTO3/BRTO4) and BRASIL TELECOM PARTICIPAÇÕES S.A. (NYSE: BRP; BOVESPA: BRTP3/BRTP4) announce that, after three months of operation, Brasil Telecom GSM exceeded the mark of half million cell phones, surpassing the target agreed with shareholders and investors. The key factors for the success reached by Brasil Telecom GSM were the innovative and revolutionary launch offer $#150; “Pula-Pula” - and the strength of Brasil Telecom’s brand in Region II.

As requested by clients and partners, Brasil Telecom GSM is launching “Pula-Pula de Verão” (Pula-Pula Summer), a new offer that will allow more people to adhere to the Pula-Pula system, using this benefit up to 2009. The “Pula-Pula de Verão” will be valid to the mobile phones activated from January 1st, 2005 to February 8th, 2005.

In the post-paid version, each time Brasil Telecom GSM client pays its bill, he receives credits in the same amount to be used in the following month. And in the pre-paid version, each minute received in calls by pre-paid clients is converted into credits for the following month.
